Abstract

The automation level of low-voltage distribution network is far behind that of medium-voltage distribution network.For achieving fault identification

isolation and power transfer of low-voltage distribution network

the optimal allocation method of section and loop switches in low-voltage distribution network is proposed.Firstly

the mutual exclusion verification method of medium and low voltage faults is proposed to identify the voltage level of the fault and accurately evaluate reliability of the low-voltage distribution network.Secondly

the concept of line average load factor is proposedand the optimization model of section switch and loop switch is established step by step.And the optimal switch configuration scheme is obtained from such aspects as quantity

location and capacity.Finally

simulation analysis is carried out and the improvement of power supply reliability by the configuration is verified under the premise of assuring my

which can guidance for the construction of low-voltage distribution network automation.
